Hi,
I'm facing a weird problem when connecting my phone to my office PC.
The phone shows that its charging but i don't see any increase in the battery percentage even after an hour. In fact, i noticed the battery drains a bit faster when connected via USB.
Just to confirm this, I installed ampere and noticed that my phone is charging at -400mA which is ridiculously strange. I have never seen something like that on any phone that i have ever used.
I thought the problem might be with the stock ROM. But its not. Things i've tried
1) Reflash stock ROM. No changes
2) Flash CM13. No changes
3) Use a different USB cable. No change
4) Use a different system in my office. No change
Things i have not tried so far
-Connect to my home PC. Could the issue be because the drivers cannot be installed on my work system? I used to charge my Nexus 5 with the same USB cable on the same system before. But this is really strange.
I use the Moto E 2015 Xt1506 Otus. Please let me know if someone has faced this problem before and has found a fix for this.
Currently i'm on CM13 and would prefer not to go back to stock.
Thanks.
If you get same behaviour with stock ROM and multiple systems, then it has to be a hardware issue.

Hi guys,
I'm having some problems with my S2's USB port. I've been combing the forums to see if I can find something, but no luck. Let me describe the symptoms and everything I tried.
Whenever I plug my phone in, it doesn't show that it's charging, but the battery is getting filled. USB also doesn't work. Rebooting the phone with the power cable plugged in shows that the phone is charging. Doing the same with the USB only made it charge but not work in USB mode. The battery life is also crappy, as the phone never goes into deep sleep (not even with the Deep Sleep app).
First I thought that the USB board might be faulty. I exchanged that (yes, the revision matches). The problem still persisted. I then tried to reflash the device with different versions of stock ROMs (ICS and JB). Same thing. I then tried flashing the Siyah kernel. That solved a small part of it. Restarting the phone while connected to the PC will make the phone be recognized as a USB device. I also installed CM 10.1. Tried it out with the Dorimanx kernel, still nothing.
My next plans are to use the NukeROM script (tried it before, but nothing) and try fiddling with different ROMs. If anyone has any more ideas, I'd really appreciate it.
Thanks,
Tudor

Did you ever try to use another, USB cable, USB port or even computer to connect your phone? If not, try this first. It is just to make sure you are not trying to fix the problem on the wrong side of the USB cable
Oh yeah, forgot to mention. Tried multiple ports with multiple cables on multiple PCs.

Awkward, in this case likely to be a hardware problem, but you mentioned it isnt. I never seen something like this.

I could live with the USB thing, but the not going to deep sleep is really a phone killer. The battery only lasts a few hours on idle.

Use BetterBatteryStats then. It will help you find the problem.

I've been using it (even got the paid version). Doesn't really show anything useful. Also, correct me if I'm wrong, it should show me any problematic apps I have installed. Seeing as how I've been wiping like crazy, I don't think it's an issue due to some app.

Wow... That definitely depends on the observer

If you think it's a hardware issue It would probably be best to bring the phone to a Samsung repair center.
Might just buy a new phone. I just wanted to see if anybody ever had the problem before.
Hi All,
Recently rooted my phone with a custom kernel and the phone does not charge when powered off for both wall USB or PC USB. It displays the grey charging battery and after 1 minute switches to the same graphic but with actual battery level and %. If I'm charging via computer, I can hear it make a USB connection sound at this point and after 5-10 seconds it disconnects. and the grey battery graphic comes back. And then this whole process repeats over and over again. The phone charges perfectly when its ON though, no problems at all! Only when its OFF do I have this issue.
I've tried Siyah, Speedmod, Dorimanx kernels with a combination of ROMs but it always has the same issue. Flashing back to Stock ROM fixes this offline charging issue. I think the issue is Kernel. The cable is not a problem cause I've switched it and I've cleaned the USB port on the phone. Changing back to stock ROM always works.
Anyone else have this problem? It's a serious one because if the battery ever dies out on me, I won't be able to charge it back unless I use an external charger.
any ideas..
Maybe it's battery related. Try another one.
Is anyone else experiencing this on LP roms?
I'm currently on 5.1.1 and if I unplug from the charger, the LED stays on and the battery percentage icon continues spinning as if it is charging.
When this happens, the battery drains abnormally quickly unless I reboot to get rid of it.
It also stops it from charging if I plug it back on the charger.
Extremely annoying, I might try reverting to an older 5.0 ROM and see if it still has the problem, maybe it's my device and not the ROM but would love to know if anyone else has come across this problem...?
obviously you're on a custom rom since the Z2 doesn't have 5.1.1 yet, so which one ?
I've recently tried multiple 5.1 roms, but never had this issue, but maybe it came up in newer builds, not sure.
You could try using other 5.1.1 rom to see if you still have the same issue. If it doesn't then you can inform the developer of your rom
thanks people's
Yes, a custom rom, I tried several other new roms and they are all exhibiting this problem for me.
I also tried reverting to a previous backup of a different 5.0.1 ROM and the problem still exists, and I'm sure the problem wasn't in that ROM when I originally used it so maybe it's coming from somewhere else.
I might try reverting to a stock rom and see what happens

Repair with PC companion or flashtool with stock ftf
I have this LED problem even on my stock phone 4.4.4 and 5.0.2. haven't noticed battery drain
I think i have narrowed it down to a bad usb cable(s) not supplying enough power to charge the phone. I have replicated this many times
I don't think it's the cable, I've tried multiples and it will charge fine using the magnetic adapter, I can also access the device files without a problem (MTP/ADB).
I've flashed the latest stock ftf (specifically D6503_23.1.A.0.726_UK+Generic.ftf) and it now shows the newer charging screen when the phone is off and plugged in, but it still has the same problem. Even when powered off it doesn't charge properly, the percentage just goes down even though the LED is on and the screen says charging. If I unplug the usb cable the light stays on and it still indicates as charging and drains abnormally.
Thought I should also mention, no matter what ROM I use (stock/custom) the auto-rotate behaves weirdly and the screen will auto rotate even when the setting is off.
Edit:
If anyone else if having this problem, it is most likely due to the magnetic charger damaging the board:

Hi,
long story short: I connected my Z5C to a bad (apparently, I don't want to test ) charger and now I have some strange issues. Is there any change that my h/w isn't fried?
Full story: As I said I connected my Z5C (newest CyanogenMod provided here) to a charger and it instantly did a hard reset. Afterwards it did turn on and continued to work for some time. As I was on the road at that time I could not charge it elsewhere and later that day it ran out of power. When I tried to charge it with a known good charger some days later, it did not boot. I suspect the boot process to healthd or whatever draws this cool animation takes more power than my working but small charger provided.
It did charge at my laptop, especially when I put it into fastboot mode.
Now thats where I am stuck; the phone won't turn off completely and keeps rebooting when I turn it off (via os menu or hard reset, no chance).
I can charge it after it runs out of power (managed to charge to 100%), but it won't charge if I unplug and replug it. It is not recognised by a pc after I reconnect it one or two times (checked with device manager and lsusb), only chance to get to fastboot or flash mode again is drain the battery to 0%. It does show a loading animation and I can boot into android from there. Battery drain in Android seems to be a little higher than usual (100 to 0 after 2 1/2 days of pure standby without any radio stuff on).
I have already reflashed the original Sony firmware and erased everything that came to my mind (cache, data....).
Any hope that I did not kill some piece of hardware?
Thanks for your answers, any help appreciated
tell me more about your z5c's software, why you mentioned Cynogenmod? did you flash it with cynogenmod?
seems to me that z5c was running on custom rom and did not support fast chargers and bricked your device!
if that so, try flashing it using flashtool with original stockrom.
i don't wana go in to details however there is possiblity that battery.sys file is corrupt and atleast I was never able to fix my LT18i when it got bricked and battery status use to become zero in 2 seconds and android keep rebooting, later it got silent for good! no charge no nothing and i still have the device sitting. I was running it on coconut (cynogenmod) when all this happened!
Thanks for your reply.
The charger was no kind fast charger, just a common 12V to USB adapter with an output of 800mA (when it worked). I was running CM 13 when I connected it to the bad charger, but as I mentioned I have since then reflashed it with Stock ROM. No real improvement.
I have continued trying and I found out that the device seems to believe it is still connected via usb.
Code:
cat /sys/class/power_supply/usb/present
gives me "1" with nothing connected, can you check if this is normal?
The file is -rw-r-- r--, would changing its value change anything or is it just some kernel thing (can't check, don't have root permissions now as I flashed Stock ROM)?
Also after I charged it on my PC today it still shows me the notifications for USB connection and adb (I can add a screenshot if necessary), also looks like it still believes to be connected.
It seems I found the solution: I was playing a bit with a USB-OTG adapter (the ones to connect regular usb devices like keyboards or storage to your phone). After I connected a USB keyboard I tried (just for fun) if the Linux "Magic" SysRq hotkeys were enabled. So I did press Alt-Print-o, which is the Linux hotkey for "turn off now". It did not turn off, it also stayed off (no instant reboot). After I started the phone again it also properly turned off via the power menu!
I will have to test whether the charging issues are fixed, too, but as far as I can tell the problem seemed to be something software-related
Sadly did not work for long. I think I will go for official repair, think this is still cheaper than buying a new phone (after completely killing it with some DIY "repair" attempt). This annoying brick simply does not turn off, no matter what I do (apart from draining battery to 0%). Guess its my fault, still to afraid to try that broken charger again.
Hi all,
My phone suddenly stopped taking a charge while I was setting up the pixel experience 8.1 rom I downloaded from here. Normally I would assume it was hardware but it seemed to happen just after I flashed pixel and was rebooting to set up supersu and xposed, so I was wondering if it might be software?
Doesn't charge or connect to pc when it twrp, or when powered off either though. And I have flashed lineage 14.1 instead and still isn't charging. I've not had any problems with the USB socket so far, and no amount of wiggling around or cleaning the contacts is working now. I have tried several cables and power supplies, they all work on my other phone.
Is there anything software wise that would still be a problem after flashing lineage? Or should I just order a new socket?
Can anyone just tell me if there's any part of the software a custom rom could alter that would affect ability to charge when the phone is off?
